To Your Wallet. Wow is this stuff expensive. Seems to be at about 25 dollars per sprue. But I do note that recently I have been looking for some plastic more traditional fantasy/medieval terrain and have not found many cheap/good options here in the states. There are very few plastic options, the laser cut stuff seems to have to be shipped in from overseas, and the resin stuff is a bit fragile to be using with my kids. On average the stuff seems to run about 30 dollars a piece so GW is pretty inline with that.
I have a reasonable table of 40K terrain with craters, crashed lander, and cities of death buildings, but nothing really for fantasy. All we have is the ruined tower from the Bones Dragon's Don't Share and it is still pretty warped so not assembled yet.
What are everyones favorite piece of purchased fantasy terrain?
